Depending on the reaction conditions, N,N’,N’’-tris(benzylamino)guanidinium salts can react with carboxylic acid chlorides to form either symmetrical N,N’,N’’-tris(N-acyl-N-benzylamido)guanidines 6 or mesoionic 4-amino-1,2,4-triazolium-3-hydrazinides 7. The latter were converted into 1,2,4-triazolium salts by protonation or methylation at the hydrazinide nitrogen atom. Neutral 1,2,4-triazoles 10 were obtained by catalytic hydrogenation of an N-benzyl derivative. Crystal structure analyses of a 4-benzylamino-1,2,4-triazolium-3-hydrazinide and of two derived 1,2,4-triazolium salts are presented.

Pharmacological Testing

2-Dimethylaminoethyl esters of 2,2-dimethylpropanoic, heptanoic, octanoic, decanoic, hexadecanoic, cyclopentylacetic, cycloheptylacetic, 2-cyclopentylhexanoic, (4-chlorophenoxy)fumaric, and 2-(4-chlorophenoxy)succinic acid were prepared by reactions of the acid chlorides with 2-dimethylaminoethanol and were transformed to crystalline salts for pharmacological testing. The ester IX (hydrogen fumarate V⁄FB-14 005) was found to antagonize significantly halothan amnesia in rats and the ester X (hydrogen fumarate V⁄FB-14004) proved to be an anticholinergic spasmolytic agent.
